Android console displays: W/art: Attempt to remove non-JNI local reference

I've just setup my first Cordova project and installed OneSignal push notifications. This is all working as I expect, however the Android Developer Tools are showing this in the console:

W/art: Attempt to remove non-JNI local reference, dumping thread
W/art: Attempt to remove non-JNI local reference, dumping thread

This message is constantly output while the app is running.

What does it mean and how can I resolve whatever issue there is?

The entries are not related to OneSignal. From the following threads this looks to be a bug with the WebView and can happen more often on enumerators when use host GPU is off. See the below threads referring to this.
